Hey fellow Earthshakers. Having some trouble with my shaker motor.
It's got me totally stumped.
Here’s the issue:
When the shaker motor and pops are both activated at the same time during gameplay they blow a fuse.
The shaker alone works during the game or in test mode likewise with the pops.
If you unplug the shaker motor the pops work fine and game plays without issue and that fuse (F3) doesn’t blow.
What I’ve tested:
The diode, resistor and transistor on the high power aux board (shaker board)
The transistor on the CPU that control the shaker.
The 0 Ohm resistor that the shaker and pops use on the main Aux board has been replaced. (W4 I think?)
The shaker was newly installed by the previous owner when he bought it, this one here: https://www.alliedelec.com/product/rs-pro-by-allied/3213192/71516156/
(some background that may or not be important: when i went to pick up the game the previous owner said the F3 fuse had just blown so he unplugged the shaker and threw a new fuse in and suggested it could be that the weights were coming into contact with the wire contacts. I've ruled that out and because he told me he didn't use the shaker when he played the game, now I'm suspecting the new motor he installed is somehow faulty. I'm more than willing to replace the motor but not sure how to determine if the motor is at fault before I spend the money on replacing it.)
